RAILROAD SCALE.

Application filed October 1"?, 1924. Serial No. 744,141.

This invention is a railroad scale primarily. One feature of the inventionconsists in arranging the intermediate i bearings for carrying the load on the cross beams vertically below the railway rails so that the load will be directly over the bearing, and in order to lengthenv the cross levers as much as possible to obtain better leverage, they are arranged obliquely to the intermediate lever, instead of as at right angles as heretofore, and are carried on said bean/i by angularly adjustable bearing` bloclrs or `plates rendering such angular arrangement of levers practical. This enables said cross levers to receive the load at a point immediately below the railway rails and to trans mit the load to the intermediate lever without reducing the length thereoit and with as great length thereof as possible.

Another feat-ure ot the invention consists in a compound bearing bloclr consisting oit upper and lower bearing plates and intermediate insertable plates, whereby the vertical thickness ot the bearing blocl: con struction may be altered or adjusted.

Another feature of the invention consists in mounting the transmitting end of the ini t-ermediate lever on another transmitting lever by means of a bearingconstruction having two bearing plates at `right angles to each other and rollers between said bearing plates parallel with one of said bearing bloclrs, preferably the one receiving the transmitting end of the intermediate lever, whereby the changes in said levers due to expansion or contraction or any other caus will be taken up by said bearing construe tion.l

The full nature of the invention will be understood from the accompanying drawings and the following description and claims. p

In the drawings, Figure. l is a central vertical section through a railway track and load supporting beams, with an end eleva tion of the leverage or scale construction, parts being omitted. Fig. 2 is raplan view olf a portion of the scale mechanism shown in Fig. 1. Fig. 3 is a side elevation oit a compound bearing block ior the transmitting end of the cross levers. Fie". i is a plan view oi' what is shown in Fig. 3. Fig. 5

is a vertical transverse section ot the bearing construction for the transmitting end ot the intermediate lever.

In the drawings, there is shown herein railway rails 10 ot' a railway track on stands 11 carried by crossvbeams 12 which in turn are carried by the -beams 18 immediately under the railway rails.

Below said railway construction the scale construction is mounted, a part or one end oi which is herein shown. It consists of a pair of transverse levers 15 receiving the load from the railway rails, an intermediate lever 16 transmitting the load fr in the levers 15 to the lever 17 which transmits the load to the weight-indicating mechanismv7 not shown.

in the ull scale apparatus, which is not here shown, there is a set oi cross levers 15 and the longitudinal levers 16 at each end oi the scale, and on each side ot the lever 17.

Each cross beam is ulcrumed at its outer end on a stand Q0 and receives a load inten mediate its length, in this construction, by a bearing 21, vertically under the railway rail. ln said bearing there is a load blocl; 22 on which the beam 13 rests. One ifea-ture of this invention consists in mounting the bearings Q1 tor the cross levers vertically under the railway rail as is very desirable. One ditliculty about ,this mounting is that it the cross levers 15 are at a right anale to the intermediate lever, the levers 1"" too short, for the distance between the railway rails is iiXed. This diiiiculty is over come'herein by lengtherring` the cross le" 15 or, at least, mal-:ing them the same as heretofore, but mounting them obli to the railway rails and to the lever 1"( indicated in Figs. 2 and 3. Hence, the lrni edge bearings Q1 on the cross iever l5 tint support the load bloeit 22 are at an `e not directly transverse to the lever iat is, the knife edges 21 are parallel with the railway rails, but not dire "ly trai l' of the cross levers which are oblique to the railway rails instead oit at a right angle thereto. Likewise at the tra` smitting endv ot each cross lever there is bearing construction.

The lrniie edges 25 extend transversely across the cross levers 15 and rests in a bearing groove 26 on a bearing plate Q7. .his bearing groove 26 may be a hardened bearing insert or not, as desired. The bearing plate 27 rests upon another bearing plate 28 with intermediate iilling plates 29 and the a change in th e 1GOy lovverl bearing; plate 27' has a bearing;l groove 30 in it that rests on a lrniie edge 3l on the intermediate lever lo. The bearing' grooves or surfaces 26 and. 30 are not at right angles te each other. The lover bearing surface SO is at right angles to the intermediate lev r 16, vf'hereas tl e upperl bearing surface is oerpendicular to the cross levers l5 ano the railway rails and extends transversely oit the cross lever to receive t i knife edge 25 thereot. The be 'fing plates 2T and 28 are anf-ularly adjustable so as to enable one ol them of varving lengths, and ti i getlier by three lugs on the i Vt plwg; which overlap the oi the iilline' k 29 and l-ovver plate r- .llie bearir L 29 are to the purpose ot inc-reasll 'en thickness of the double bearing' bloelr eonstruction jus described bv inserting or removing;v one o1 more of said plat-Jrs a Ld they are held in position bv the lugs The intermediate lever l@ is ilulcrun the earing; bloel; 35 near its lon v end and at its load transmit is a bearing; construction b lever 17 which is illustrated in load transmitting end ot t lever 16 rests upon a of the bearing` bloelr 37 t a roller 38 transversely ot the beam 16.. These rollers supported in a bearing block belovv the i has a bearing; surface l0 extending1 at right to the bearing surface 86 of the block above and transv.rseljv7 oit the load transinitting` beam 17. The adjacent faces o1 the blocks 37 and 39 are correspondingly gro-overl tor holding the roller 38, but thev are nv'iuened grooves and the purpose of this beL ring` construction is to adapt it lor constant servlee regardless of the expansion and contraction ot the levers 16 and l? or iv minor change in their relation trom anj,T Cause.
